DESCRIPTION. Similar to M. setulosus sp.n. except as follows: BL 10.7 mm. Body ( Fig. 4 View Figs 4–6 ). Microsculpture obliterate on head, with isodiametric meshes hardly traceable on vertex but medially; consisting of slightly transverse and highly superficial meshes on pronotum. Body, including pro- and metafemora ventrally, rather densely setulose; this erect and short pilosity is very distinct on genae and along sides of pronotum.

Head: HnW/OL 2.50, genae three fourths as long as eyes, GL/OL 0.75. Frontal foveae extended slightly to eyes. Vertex with a pair of shallow round pits between eyes.

Pronotum wide due to acute and very prominent lateral angles, PW/PL 1.55, PW/HW 1.42, PLw/PL 0.39, PB/PA 1.12. Sides sinuate just in front of lateral angles, deeply sinuate behind, and distinctly diverging in basal fifth toward acute and pointed basal angles; apical angles obtuse, with extreme tips barely projecting. Disc very convex, without lateral bead or explanate lateral margin in front of lateral angle. Basal transverse impression interrupted just medially. Basal foveae very deep basally, then extended parallel to lateral edge nearly to the level of lateral angles. Explanate, slightly reflexed and densely to confluently punctate areas outside the extensions of basal foveae substituted for explanate lateral margins; this latter reduced to a fine lateral bead. Propleura tumid, in dorsal view just traceable between lateral and basal angles.

Elytra: EL/EW 1.42, EW/PW 1.48, with sides barely concave a third from base. Striae very finely punctate; intervals vaguely punctulate (where setulose). USS: 20–21.

Legs: protarsus 4–carinate, lateral carinae fine, median ones faint. Profemur with one anterior seta, 2–3 setae additional and proximal to posterior medioventral seta and one seta unilaterally additional to posterobasal seta.

Female gonocoxite with four ventral ensiform setae.

DIAGNOSIS. The species is very distinctive in having the setulose body and stellate pronotum without explanate lateral margin or lateral bead anterior to acute and strongly projecting lateral angles.

NAME. Refers to the stellate shape of the pronotum.

GEOGRAPHIC DISTRIBUTION.The type locality only.
